3.G.1

Los Angeles Unified School District Ÿ Grade3
Organized by Standards
2016-2017
DOMAIN: Geometry
CLUSTER: Reason with shapes and their attributes. s/a
Big Idea: Two- dimensional shapes can be described, classified, and analyzed by their attributes. A shape’s location in space can be described quantitatively.
Enduring Understandings: Plane shapes have many properties that make them different from one another. Polygons can be put together or taken apart to make
other polygons. Polygons can be described and classified by their sides and angles. A region can be divided into equal-sized parts in different ways, and equalsized parts have the same area but not necessarily the same shape.
CONTENT
PRACTICE
MP1 Make sense of problems and persevere in solving them.
MP2 Reason abstractly and quantitatively.
MP3 Construct viable arguments and critique the reasoning of others.
MP4 Model with mathematics.
MP5 Use appropriate tools strategically.
MP6 Attend to precision.
MP7 Look for and make use of structure.
MP8 Look for and express regularity in repeated reasoning.
STANDARDS
FOR MATHEMATICAL
3.G.1 Understand that shapes in different categories (e.g. rhombuses,
rectangles, and others) many share attributes (e.g., having four sides), and
that the shared attributes can define a larger category (e.g.,
quadrilaterals). Recognize rhombuses, rectangles, and squares as examples
of quadrilaterals, and draw examples of quadrilaterals that do not belong
to any of the subcategories.
